Windows7 x64 + Ruby 1.9.3 p545 (i386-mingw32) 上で Nokogiri をインストールしようとしたらエラーが出るようで。

C:\home\Downloads\DLprog\ruby\gem>gem install nokogiri --platform x86-mingw32

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

色々試してみたけれど、どうやら事前に mini_portile 0.6.0 をインストールしておかないとエラーがでる模様。

gem install mini_portile
gem install nokogiri

> gem list | grep "mini_portile\|nokogiri"

mini_portile (0.6.0, 0.5.3)
nokogiri (1.6.2.1 x86-mingw32)

> ruby -r nokogiri -e "p Nokogiri::VERSION"

"1.6.2.1"
